Some background may be found here (relating to debian's gcc-4.4 package which
has TLS backported):
http://lists.debian.org/debian-68k/2010/10/msg00037.html
(In that compiler, the code generated is an offset against TLSLDO, but shows
the same bug.)
The bug was initially filed for binutils (since closed as invalid):
http://sourceware.org/bugzilla/show_bug.cgi?id=12157
Bug may be worked around with -O0.
